There are just a few people on Earth who could have put together the show that Larry Gagosian recently opened. Only a mega-gallery like his, with huge spaces in multiple cities, could borrow 27 Monets, including an astounding 11 from the Musée Marmottan, the Paris museum housing the largest Monet collection in the world. "Claude Monet: Late Work" is the kind of undertaking that we usually leave to institutions, and if MoMA or the Met had only borrowed those canvases and hung a banner saying MONET FROM THE MUSÉE MARMOTTAN, either would’ve had a hit.
